javascript - 包含具有 "ing"的字符串的过滤器数组？

Question

在 Javascript 中，有没有一种方法可以从数组中选择包含某些内容的单词。例如，["swimming", "basketball", "chess", "rowing"]，我只想选择包含“-ing”的项目并向它们应用字符串。

"I go" + "swimming", ect.

相反，有没有办法选择不包含该参数的项目。没有“-ing”的单词

"I play" + "basketball", ect

Answer 1

您可以使用:

• Array.prototype.map()
• Array.prototype.includes()
• Arrow functions

let arr = ["swimming", "basketball", "chess", "rowing"];
let result = arr.map(s => (s.includes("ing")? "I go ": "I play ") + s);
console.log(result);

或者，您可以使用 Array.prototype.filter() 过滤此数组并对每个数组执行您想要的任何操作。

let arr = ["swimming", "basketball", "chess", "rowing"];

let strWithIng = arr.filter(s => s.includes("ing"));
let strWithoutIng = arr.filter(s => !s.includes("ing"));

console.log(strWithIng);
console.log(strWithoutIng);
